Application filed November 18, 1913. Serial No. 801,735.

To all whom it may concern:

Be it known that I, JOHN L. ESLINGER, a citizen of the United States, residing at 'lucumcari, in the county of Quay and State of New Mexico, have invented new and useful Improvements in Automatic Pump-Reg ulators, of which the following is a specification.

This invention relates to feedwater regulators for steam boilers, the object in view being to provide means for automatically regulating the amount of water fed to the boiler so as to maintain a certain level of water in the boiler irrespective of the load imposed thereon, the water level being main tained by the action of a feed-water pump which is controlled by the level of water contained in a reservoir forming an extension of the water space in the boiler.

' WVith the above and other objects in view,

7 the invention consists in the construction,

combination and arrangement of parts, as will hereinafter be more fullydescribed, illustrated and claimed.

In the accompanying drawings: Figure l is a side elevation partly in section of the reservoir, showing upper and lower connec tions to the steam boiler. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation on a reduced scale showing the application of thedevice to a boiler and pump.

In carrying out the present invention, I employ a reservoir A of any suitable capacity in accordance with thecapacity of the boiler in connection with which the reservoir is used. i

The reservoir A is preferably formed in the shape illustrated in the plan view Fig.

so as to provide for the reception therein of a risingand falling float B which moves upwardly and downwardly in accordance with the level of water contained in the reservoir A, said reservoir being connected with the boiler by means of an upper steam pipe connection a and a lower water connection Z), the reservoir therefore having a water space and a steam space correspond ing in level with the water and steam of the boller.

spaces The float B is mounted one end of a' float lever G the same being formed with a slot 0' to receive a pin a on a support or Specification of Letters Patent.

bracket D fastened to the inside of thereservoir A as shown in Fig. l. The support D is shown as provided with a number of perforations (Z to admit of the adjustment of the pin 0 thereby correspondingly adjusting the height ofthe float B to provide for the earlier or later operation of the steam valve controlled by the float B. Connected pivotally to the opposite end of the float lever C is a rod E which extends upwardly through a guide F also through a stuffing box H the reservoir, said rod being connected pivotally to a steam valve stem or operating rod G, said valve being located in the lead 6 between the steam space of the boiler and the pump I which forces the water to the boiler.

,From the foregoing description it will now be understood that when the water is at the desired level in the boiler, the same level of water in the reservoir will hold the float B elevated andvery little or no steam 'will be admitted to the pump. Therefore,

no water will be pumped into the boiler at within the reservoir and at the top of this time. As soon as the level of water in the boiler falls, the float B will correspondingly fall thereby 'operatingthe stem G to open the pump controlling steam valve. This allows steam to pass'to the pumpand the latter operates immediately to force waterto the boiler. The amount of steam passing to the pump thus varies in accordance with the level of water in the boiler and reservoir. The higher the level in said boiler and reservoir, the less steam will there be admitted to operate the pump thus making the device entirely automatic in operathe top of said cylinder and having a stuff- In testimony whereof I aflix my signature ing box through which said rod passes, an in presence of two Witnesses.
